Mobile Application Testing

Secure your mobile presence.

Security assessment of iOS and Android applications covering client-side vulnerabilities, backend API security, data storage, and platform-specific attack vectors.

Overview

Mobile applications face unique security challenges: data stored on devices users control, communication over untrusted networks, and platform-specific attack vectors. Our mobile application testing examines the entire mobile ecosystem—the app itself, its communication with backend services, and how data is stored and protected on the device.

What We Test

Our mobile application testing engagements cover these key areas:

Data Storage

Local storage, keychain/keystore usage, database encryption, and caching mechanisms evaluated for sensitive data exposure.

Network Security

TLS implementation, certificate pinning, and API communication tested for interception vulnerabilities.

Authentication

Login mechanisms, session handling, biometric authentication, and token storage analyzed for weaknesses.

Binary Protections

Reverse engineering resistance, code obfuscation, tampering detection, and jailbreak/root detection evaluated.

Backend APIs

Mobile-specific API endpoints tested for authentication bypass, data exposure, and business logic flaws.

Platform Permissions

Permission requests reviewed for over-privilege, and IPC/intent handling tested for security weaknesses.

Our Approach

Our mobile testing follows the OWASP Mobile Application Security Verification Standard (MASVS) and includes both static analysis of the application binary and dynamic testing of runtime behavior.

1

Static Analysis

We decompile and analyze the application binary for hardcoded secrets, insecure configurations, and vulnerable code patterns.

2

Dynamic Analysis

We test the running application on real devices or emulators, intercepting traffic and manipulating app behavior.

3

API Testing

Backend APIs are tested using the mobile app as a client, identifying mobile-specific vulnerabilities and access control issues.

4

Data Analysis

We examine local storage, logs, and caches for sensitive data that persists after logout or app closure.

Common Findings

These are issues we frequently discover during mobile application testing engagements:

Insecure Data Storage

High

Sensitive data stored in plaintext in local databases, shared preferences, or application logs.

Missing Certificate Pinning

Medium

Applications vulnerable to man-in-the-middle attacks through proxy interception of API traffic.

Hardcoded Secrets

High

API keys, credentials, or encryption keys embedded in the application binary, extractable through reverse engineering.

Weak Authentication

High

Insufficient validation of user identity, bypassable biometric authentication, or insecure session handling.

Debug Features in Production

Medium

Logging, debug endpoints, or testing features left enabled in production builds.

Insufficient Binary Protections

Low

Applications easily reverse engineered due to lack of obfuscation or anti-tampering controls.

Common Questions

Do you test iOS, Android, or both?

We test both platforms. If you have apps on both iOS and Android, we recommend testing both—each platform has unique vulnerabilities. If budget is constrained, we can prioritize based on your user base.

Do you need access to the source code?

No, but it helps. We can perform black-box testing using only the published app. Source code access enables more thorough analysis and is required for certain compliance frameworks.

What about backend API security?

Mobile app testing includes backend API testing—we examine the entire attack surface. For apps with shared APIs (web and mobile), we may recommend combined application testing for comprehensive coverage.
